The PZ-70A series is a digital intelligent absolute pressure transmitter developed based on a capacitive measuring unit. The measuring unit is composed of a ceramic diaphragm with a purity of more than 99.9%, featuring gas type non-discrimination, high precision, and no hysteresis. This series of products adopts the most advanced digital processing technology throughout the entire process, which greatly improves the measurement accuracy and intelligence level of the sensor. It can directly output pressure and temperature values in digital signals, adapting to the digital trend of process control.

The digital circuit can also provide sensor noise suppression function and improve EMC compatibility, long-term stability and temperature compensation accuracy. Meanwhile, considering customers' usage habits of traditional capacitance diaphragm gauges, this product retains the traditional analog signal output function and can realize seamless replacement of all traditional models of capacitance diaphragm gauges.
